About Merge PDF files
Merging PDFs is one of the most common document tasks: putting scanned pages together, joining a report with its appendix, or sending one tidy file instead of many attachments. This tool copies every page from your files into a single new PDF without re-compressing them, so fonts, images and links come through exactly as they were.
Because the work is done by your own browser, merging is fast even on a slow connection, and nothing you merge is ever stored anywhere but your device.
Any number of files
Merge two PDFs or fifty. There is no file limit and no watermark on the result.
Private by design
Merging happens inside your browser. Your documents are never uploaded to a server.
Keeps original quality
Pages are copied as they are, so text stays sharp and searchable.
Frequently asked questions
Is it free to merge PDF files?
Yes. Merging is completely free, with no sign-up, no daily limits and no watermark added to your document.
Are my files uploaded to your server?
No. The merge runs in your web browser using JavaScript. Your PDFs never leave your computer or phone.
How do I change the order of the PDFs?
Drag a file card and drop it in a new position. The order of the cards, from left to right, is the order of the merged document.
Can I merge password-protected PDFs?
Not yet. Remove the password with the program that created the PDF first, then merge it here.
Does merging reduce quality?
No. Pages are copied without being re-compressed, so the merged PDF looks exactly like the originals.
